Tacoma Hard Start Finally Caught On Video

Nice truck!

 

Do you ever pump the gas pedal when you start?

 

No reason to pause, the fuel system is already pressurized even when the vehicle is off and left for long periods of time. The vehicle will do a self check few hours after truck is shut off. I know first hand when I installed my supercharger I go and change the injectors out and disconnect all fuel lines to the engine and when I did I got sprayed with fuel for days lol. Case in point absolutley no reason to pause all 3 of my tacomas did this occasionally not enough to worry about though

 

Same here.

I feel it's just Toyota quality going down the shitter.

 

Sorry, if I am re stating this since I only read the first page, but I was told it is the TPS(throttle position sensor) that gets out of wack and the motor will die, the sensor will re adjust and you are good to go.

Same thing happens on the Fuel injected bikes that I race. Not sure exactly how the TPS sensor screws up though.

 

Hey Guys mine does this too, usually only when its cold out but it has done it before during other seasons too.

After this last time, I added HEET to my gas when I filled up and after a couple weeks it still hasnt done it. I feel like it fires up better and more reliably sounding. You might just try it. IDK.

I have a 2009.

 

My 1st gen does this.

 

Yes, the system is supposed to hold pressure for a while. You are correct. But the fuel pump does not operate during the self check you mentioned. The self check is for the EVAP system.

 

My '12 has had a few hard starts as well.

 

My 2010 Sport did this after work yesterday for the first time. Real slow crank crank let off and tried again but was slow to crank. Hasnt done it at all today?? No lights were left on and it was 65 degress out.

 

This must be a V6 thing, cause in the 66xxx miles on my taco, I have never experienced this lol.

 

inferior 4.0

Isn't it a reliable engine though. Still its kinda old and doesn't put out much power at all, Toyota definitely needs to update the V6 and make a more powerful one. The Chrysler 3.6 puts out 285, toyota needs to make one that puts out at least 280.

 

Crank or cam position senors???

 

Amen to that! For the gas milage I get, I atleast want respectable HP. The 4.0 is reliable though, which is always a double thumbs up.

 

I think it's easier for everyone to relate to the noise/visual cues as opposed to text of a 'hard start'.

There seems to be a couple other threads about this same thing a couple years ago with the V6 4.0's, but no solution seems to work. Also no video that I could find either.

Bill... this sure seems exactly like the problem back around 07 with the intermittant no-start condition tsb (tsb EG011-07). Mine was doing the same thing as mentioned... had that tsb done and it was completly fixed. Why can't they do a recalibration of the ecm to correct this issue now?

 

mine just did it again yesterday and the temp was 8c this worries me because it's only done this at temps of -2 or colder sitting overnight...now its happening at warmer temps during the day...Its so intermittent I havnt been able to catch it on vid yet...Once i do i'll definetely post it...

 

Why can't they do a recalibrate now? Because we don't know if it is a calibration error, or a part failure. Until you can verify WHAT is broke, there is no way to know what to do to fix it.

 

well it sounds like that ECM reflash fixes it... so again, why cant they just keep doing it for newer trucks?

 

1. The reflash fixes a common problem, but first one needs to know that it is the EXACT same problem first.

2. Why can't they keep doing it for newer trucks? Because the programming for each successive year truck is different. A software update for Windows XP won't do anything to help even the exact same problem with a boot failure on a computer running Windows 8. Different operating system.

It is the same thing on cars. They have a complete new operating system each year. Even though tons of parts are identical, software is something that is CONSTANTLY changing.
